Configuring System and Security Aspects

To adjust settings such as time and date format, number format, or currency, select the desired country as the default country in KDE. If more than one system language is installed on your computer, you can also select different languages in which KDE should show the graphical user interface and application interfaces.

Procedure 3.14. Adjusting Regional Settings

To set your default country options, open the Personal Settings and select Regional & Accessibility+Country/Region & Language.
From Country or Region, select the desired country. If the language of the country is installed on your system, KDE automatically sets the language as the default language and shows it at the top position in the Languages list.
If needed, adjust the other country-dependent options, such as number or time and date format, on the other tabs.
If more than one language is installed on your system (as secondary languages with YaST) and you want to change the graphical interface of KDE to a different language, click Add Language on the Locale tab.
Choose Other to open a list of other languages installed on your system. Select the language for the graphical user interface. The new language is now shown at the top position in the Language list.
To confirm the changes, click Apply. All newly started applications or desktop objects now appear in the new language.
To switch to another language, re-sort the languages in the Languages list until the desired language is at the top position and apply your changes.

If you often need to enter texts in various languages, you may want to add different language layouts for your keyboard. You can then easily switch layouts when needed.

Procedure 3.15. Adding Keyboard Layouts

To add additional keyboard layouts, open the Personal Settings and select Regional & Accessibility+Keyboard Layout.
Activate Enable keyboard layouts at the top.
In the list of Available layouts, select a layout. Click Add to transfer it to the list of Active layouts.
If you added several layouts, you can change the sorting order with the help of the up and down arrow buttons.
Depending on the options you choose in the Switching Options tab an indicator or country flag appears in the system tray. With a click on the icon you can change between different keyboard layouts after you confirmed your changes with Apply.

By default, openSUSE provides various fonts commonly available in different file formats (Bitmap, TrueType, etc.). These are known as system fonts. Users can additionally install their own fonts from various collections. Such user-installed fonts are, however, only visible and available to the corresponding user.

Procedure 3.16. Installing New Fonts

To check which fonts are currently available, type the URL fonts:/ into the address field of a Konqueror session. This displays two windows: Personal and System. User-installed fonts are installed to the folder Personal. Only root can install to the System folder.

To install new fonts, proceed as follows:

Start the control center from the main menu or press Alt+F2 and enter kcontrol.
Click System Administration+Font Installer.
To update system fonts, click Administrator Mode and enter the root password. Then proceed as described below.
To install fonts as a user, click Add Fonts.
In the dialog that opens, select one or more fonts for installation. The marked fonts are then installed to your personal font folder. Selecting a font shows a preview.

KDE runs a session manager that starts after your username and password are authenticated by the login process. It lets you save the status of a certain session and return to that status the next time you log in. For example, it can automatically start the applications that you were running in the most recent session or when you manually saved a session. It can save and restore the following settings:

Appearance and behavior settings, such as fonts, colors, and mouse settings.

Applications that you were running, such as a file manager or OpenOffice.org.

	Saving and Restoring Applications
You cannot save and restore applications that Session Manager does not manage. For example, if you start the vi editor from the command line in a terminal window, Session Manager cannot restore your editing session.

Procedure 3.17. Adjusting the Session Handling

To change the session handling options, open the Personal Settings and click KDE Components+Session Manager. The groups General and Default Shutdown Option hold options for the confirmation dialog that usually appears on logout.
By default, Session Manager restores the applications that were running when you logged out from the previous session, enabling an automatic start of these applications.
To be able to save a certain session manually and restore this session each time you log in to KDE, select Restore manually saved sessions. This adds a new menu item, Save Session, to your main menu. After a session is saved, KDE automatically restores the saved session on each login.
To start with a “fresh” session each time you log in, select Start with an empty session.
Click Apply to confirm your changes.

By default, you define the settings for KWallet password manager with the help of a wizard when you use KWallet for the first time. You can adjust the initial settings at any time to increase security.

Procedure 3.18. Adjusting KWallet Settings

If KWallet is already started, click the KWallet symbol in the panel and select Configure Wallet. Otherwise, open KDE control center and click Security & Privacy+KDE Wallet.
If KWallet Manager is not yet enabled, activate the respective check box at the top.
By default, a wallet is closed when the last application stops using it. To increase security, you can set a more restrictive policy: to close a wallet automatically after a period of inactivity or after start-up of the screen saver, activate the respective check boxes.
To remove the KWallet icon from the panel, deactivate Show manager in system tray. You can then only access KWallet from the main menu.
By default, KWallet stores all passwords in one wallet named kdewallet. To store local and network-related passwords in different wallets, activate Different wallet for local passwords. Click New to create an additional wallet, if needed.
